My students cant even use their names in the discussions...they are all being referred to as numbers as its tied to their matric number... Its been 2 years, any chance of an update or something about the possibility of this being done?

We need a nickname feature in Teams - with the admin option to enable or disable. For example, our office locations include Thailand, where everyone uses nicknames as their work names - but not as their first name or last name.

Yes, please! I know you can currently delete the last name, but it's a hassle to keep doing it that way. Would very much prefer the first name or nickname route to keep the conversation human. :) Thanks.

There are reasons for display name conventions other than first name + last name. Teams should either enable a social collaboration nickname or at least take the first name user attribute into account, when shortening a mention.

+1 on this. At my organization, they add in our parent co. AND business unit acronyms in our display name which ends up with a terribly unsightly @mention...if you have two last names and a middle name...forget about it..

I just set up our MS Teams and the first thing I noticed was how annoying the LastName, FirstName is, so I went searching to find a way to update display name. I am shocked to see there isn't an alternative. It is fine and easy to remove the last name from tagging, but users need to update their profile name for their own posts too. This is especially important in our workplace where people have American nick names.
